Final answer:
The correct word to complete the sentence is 'hablé'.
Step-by-step explanation:
The correct Spanish word to complete the sentence is 'hablé'.
In the sentence 'Ayer yo hablé con mi madre por dos horas', the verb 'hablé' is in the past tense and agrees with the first-person singular subject pronoun 'yo' (meaning 'I' in English).
This indicates that the person speaking ('yo') had a conversation with their mother for two hours. The correct word choice is 'hablé' since it matches the subject and tense of the sentence.
